Whathappendinmybirthyear - A fun research tool!

You can type in a year (not sure how far back it goes, as it's really for checking what happened in the year of your birth, but can be helpful in some cases at least), and it brings up all kinds of information about what happened that year.

It types it out s-l-o-w-l-y, but I found that if you start to go to another url, a message box pops up saying it will instantly print out the whole thing if you hit "cancel" on the box.
